The Files tabs in the Resources Window give you access to servers, drives, directories, and files without having to go to Windows Explorer.
Having two Files tabs reduces the amount of file system navigation needed to work across multiple directories and drives.
Several operations-such as opening and saving files, backing up before replacing text in files, displaying thumbnails for the images in a folder, browsing to files in tag editors, and creating an image map-refer to the current directory.
The Files tabs use these rules to determine which directory is the current directory:
Options > Settings > General > Display current folder in file dialogs must be set.
You can move and dock tabs, for example to display or hide both Files tabs.
